Niels Bohr 1885 - 1962, Copenhagen, Denmark principal papers hardware software keywords see also related subjects Achievement Biography Niels Bohr was born and educated in Copenhagen, Denmark. He lived, worked, and died there, too. But his mark on science and history was worldwide. His professional work and personal convictions were part of the larger stories of the century. At the University of Copenhagen, he studied physics and played soccer (though not as well as his brother, who helped the 1908 Danish soccer team win an Olympic silver medal). After receiving his doctorate in 1911, Bohr traveled to England on a study grant and worked under J.J. Thomson, who had discovered the electron 15 years earlier. Bohr began to work on the problem of the atom's structure. Ernest Rutherford had recently suggested the atom had a miniature, dense nucleus surrounded by a cloud of nearly weightless electrons. There were a few problems with the model, however. For example, according to classical physics, the electrons orbiting the nucleus should lose energy until they spiral down into the center, collapsing the atom. Bohr proposed adding to the model the new idea of quanta put forth by Max Planck In 1912 Bohr married Margrethe Nørlund. They had six sons, one of whom, Aage, followed his father into physics and into the ranks of Nobel Prize-winners. Bohr returned to Denmark as a professor at the University of Copenhagen, and in 1920 founded the Institute for Theoretical Physics sponsored by the Carlsberg brewery! Bohr remained director of the institute for the rest of his life, except for his absence during World War II. Bohr's personal warmth, good humor ("Never express yourself more clearly than you can think," he once said), and hospitality combined with world events to make Copenhagen a refuge for many of the century's greatest physicists.

Branch of Science Physicists Nationality Danish ... Scientific Families Bohr, Niels (1885-1962) Danish physicist who proposed a successful quantum model of the atom in 1913. His model assumed that (1) the electron exists at precise distances from the nucleus, (2) as long as an electron remains in one location, no energy is given off, (3) electrons have circular orbits (this is only correct for s orbitals), and (4) the angular momenta associated with allowed electron motion are integral multiples of Bohr stated the Correspondence Principle, which states that quantum mechanical formulas must reduce to the classical results in the limit of large quantum number. He also advocated a probabilistic interpretation of quantum mechanics known as the Copenhagen interpretation Bohr (Aage) Bohr (Christian) Bohr (Harald) Additional biographies: MacTutor (St. Andrews) Blaedel, N.

Other Resources Biography Niels Henrik David Bohr was born in Copenhagen on October 7, 1885, as the son of Christian Bohr, Professor of Physiology at Copenhagen University, and his wife Ellen, Adler. Niels, together with his younger brother Harald (the future Professor in Mathematics), grew up in an atmosphere most favourable to the development of his genius - his father was an eminent physiologist and was largely responsible for awakening his interest in physics while still at school, his mother came from a family distinguished in the field of education. After matriculation at the Gammelholm Grammar School in 1903, he entered Copenhagen University where he came under the guidance of Professor C. Christiansen, a profoundly original and highly endowed physicist, and took his Master's degree in Physics in 1909 and his Doctor's degree in 1911.

Last updated: 21.10.2004 09:01:58 Niels Bohr was born in Copenhagen in Denmark in 1885. His father was a professor of physiology at the University of Copengagen. Niels attended the same university and was a distinguished soccer player as well as a brilliant student. Bohr studied at J. J. Thomson ´s Cavendish Laboratory and at Rutherford ´s laboratory. At the young age of 28, while working with Rutherford, he invented the first effective model and theory of the structure of the atom. His work ranks as one of the truly great examples of an imaginative mind at work. He was awarded the 1922 Nobel Prize for physics for his study of the structure of atoms. During Worls War 2, Bohr and his family escaped from occupied Denmark to the United States. He and his son, Aage, acted as advisers at the Los Alomos Atomic Laboratories, where the atom bomb was developed. Thereafter, Bohr concerned himself with developing peaceful uses of nuclear energy. Aage Bohr, Neil´s son was awarded the Nobel Prize for physics in 1975. Optimální rozlišení - 1024x768, minimálnì 800x600.

The institute became a focal center for theoretical physics for a generation. , determined by the energy difference between the two states. E = E E The constant h J/T) are today used as units of measure. In 1922 Bohr received the Nobel Prize in physics. Bohr deduced the correspondence principle: A quantum description of atoms must tend to the classical description for larger dimensions. He also deduced the complementarity principle: There are interactions between objects and the instruments used to observe them. Using the complementarity principle he concluded that there is always a limit to the ability of scientists to observe (and to know) atoms. With this concept he acquired an influence beyond the world of physics. In the 1930s Bohr turned to nuclear physics. In 1936 he described an atomic nucleus as resembling a liquid drop existing in different states. In 1940 he and John Archibald Wheeler devised a theory of the

For example, according to classical physics, the electrons orbiting the nucleus should lose energy until they spiral down into the center, collapsing the atom. Bohr proposed adding to the model the new idea of quanta put forth by Max Planck in 1901. That way, electrons existed at set levels of energy, that is, at fixed distances from the nucleus. If the atom absorbed energy, the electron jumped to a level further from the nucleus; if it radiated energy, it fell to a level closer to the nucleus. His model was a huge leap forward in making theory fit the experimental evidence that other physicists had found over the years. A few inaccuracies remained to be ironed out by others over the next few years, but his essential idea was proved correct. He received the Nobel Prize for this work in 1922, and it's what he's most famous for. But he was only 37 at the time, and he didn't stop there. Among other things, he put forth the theory of the nucleus as a liquid drop, and the idea of "complementarity" that things may have a dual nature (as the electron is both particle and wave) but we can only experience one aspect at a time.
